Control lever device of industrial vehicle

Abstract

A control lever device of an industrial vehicle includes a control lever that is tiltable forward and rearward relative to a vehicle body of the industrial vehicle and that includes a control knob, a switch button that is provided on the control knob and adapted to be pushable while the control lever is operated. The switch button has a movement axis indicating a movable direction of the switch button. The movement axis is inclined forward relative to a direction orthogonal to an extending direction of the control knob so that a pushing direction of the switch button is directed rearward from the direction orthogonal to the extending direction of the control knob.

What is claimed is: 
     
       1. A control lever device of an industrial vehicle comprising:
 a control lever comprising:
 a first portion that extends obliquely rearward; 
 a second portion that is continuous with the first portion and extends rearward; and 
 a control knob that is coupled to the second portion and has a switch button provided on a raised portion protruding from an upper surface of the control knob, the control lever being tiltable forward and rearward with respect to an operator of the industrial vehicle seated in the industrial vehicle, wherein 
 
 the raised portion is provided at an intermediate position of the upper surface of the control knob and comprises an end face portion facing obliquely forward and upward, 
 the switch button is provided in a center of the end face portion of the raised portion and is adapted to be pushable while the control lever is operated, 
 an upper surface of the end face portion and an upper surface of the switch button are oblique with respect to the upper surface of the control knob, and 
 the switch button has a movement axis indicating a movable direction of the switch button, wherein the movement axis is inclined forward relative to a direction orthogonal to an extending direction of the control knob so that a pushing direction of the switch button is directed rearward and obliquely downward. 
 
     
     
       2. The control lever device of an industrial vehicle according to  claim 1 , wherein
 the control knob has a predetermined knob length in the extending direction of the control knob, and 
 an intersection of a central axis of the second portion of the control lever extending along the extending direction of the control knob and a central axis of the switch button extending along an extending direction of the switch button is located in the control knob. 
 
     
     
       3. The control lever device of an industrial vehicle according to  claim 1 , wherein
 a forward inclination angle of the pushing direction of the switch button is within a range between 20 degrees and 60 degrees. 
 
     
     
       4. The control lever device of an industrial vehicle according to  claim 1 , wherein
 the control lever is a clamping control lever adapted to control a pair of clamp arms for holding a load therebetween.
